In a statement posted on her official website, McCarthy said during her annual physical her doctor diagnosed her with a treatable form of the disease.

“Several diagnostic tests have led to a diagnosis of lung cancer. A treatment plan will begin soon and I look forward to its successful completion. My doctor at Memorial Sloan-Kettering Cancer Center, where I’ll receive my treatment, has told me that I begin my treatment in good physical health and that he looks forward to my return to work after I recover. My family and I will appreciate privacy while I undergo my treatment,” the statement read in part.

McCarthy noted she will take some time off from the day-to-day rigors of legislating as she undergoes treatment.

“There will be some tough days ahead and I will have to miss activities in Washington during my treatment in New York, but I will continue to be a strong advocate for the 4th Congressional District — and I remain committed to improving Long Island’s schools, improving public health and safety, improving our economy, and protecting our seniors and veterans. My capable and longtime staff will continue to support the needs of my constituents,” the statement read.

McCarthy is currently serving her eighth term in office. She was first elected to the House of Representatives in 1996.

“I am a fighter, as many people know, and I am committed to beating this latest challenge in my life. I’m grateful for the support and love of my family, friends, colleagues, and staff. I look forward to a successful treatment and returning to continue the mission that I’ve started as a Member of Congress,” her statement concluded.
